Liquidtight Connectors and Hubs for Liquidtight Flexible Metal Conduit General nformation and special features. - 39 Seal out oil, water, dirt, dust and fumes wherever liquidtight flexible metal conduit is used. Typical applications include food processors, beverage plants, chemical plants, dairies, machine shops, plastic fabricators, petroleum machinery, and gantry cranes. ST and STB Series For connections to threaded hubs. nsulated throat on STB protects conductors. Connectors are available with grounding lugs. Straight sizes 3/8 thru 5 ; 45 and 90, 3/8 thru 4. Straight and 90 styles in sizes 3/8 thru 2 also available with certain metric thread sizes. See page -49. STN Space-Sa ving Connectors for Enclosures Appleton STN Series makes liquidtight connections to sheet metal enclosures. Space-saving, self-locking gasketed wedge forms a perfect seal and allows more wiring room. Straight sizes 3/8 thru 4 ; 90 sizes 3/8 thru 1. STG Neoprene Sealing Gasket Assembly Steel backed, neoprene gasket assembly assures a liquidtight connection to a rough metal surface such as knockouts in steel junction boxes. Sizes 1/2 thru 4 feature bonded gasket/retainer assembly. 1/4 and 3/8 available in thermoplastic material. Female Steel ST Connectors For liquidtight connections to threaded rigid metal conduit. Sizes 3/8 thru 1. Extra-long ferrule resists pullouts. All Appleton liquidtight fittings feature a one-piece, deep-grip ferrule design that simplifies installation and prevents conduit sleeving. ts extra length and sharply defined threads provide greater surface contact with the conduit for excellent grounding continuity, greater pull-out strength (4X UL requirements)...and added protection against excessive external conduit flexing and vibration. t virtually eliminates the need for an external strain relief in many applications. External grounding lugs available on all Appleton liquidtight connectors. Where National Electrical Code permits an external equipment bonding jumper, [NEC sections 250-96(b), 501-16(b) and 502-16(b)], Appleton ST and STB connectors are offered with an integral bonded steel zinc electroplated lug. Cut-away view shows extended ferrule design for maximum grounding effectiveness. Grounding lugs also available in STN, STL and Female ST Series. Consult factory. Wire mesh strain relief available on all STB, STN, and female ST connectors. Woven stainless steel mesh sleeve alleviates flexing stress at liquidtight connection. PAGE 39
- 40 nstallation of ST, STB and STN Connectors and Hubs for Liquidtight Flexible Metal Conduit Liquidtight Connectors A B C D Using hacksaw, cut liquidtight flexible conduit making certain that the jacket and conduit are flush. (A) Place compression nut over conduit. (B) Screw ferrule onto the spiralled steel inner wall of the conduit. The firm grip of the ferrule threading against the inner conduit wall provides a continuous, permanent, positive metalto-metal ground. There are no sharp edges to cause injury to wire during or after installation. (C) Place the liquidtight flexible conduit with the ferrule into connector body. (D) Tighten compression nut as far as it will go. This will assure correct collaring of the conduit the end of the metal edge of the ferrule will curve out slightly (E) This prevents damage to the conduit jacket itself at the time of installation, and also insures against future damage from frequent flexing, jarring or vibration. Liquidtight Hubs Sealing Gasket Neoprene sealing gasket eliminates common connection problems and assures a liquidtight installation. Seals against oil, water, dirt and chemicals. Space Saving Hex-Hub Wedge Adapter Male shank of unique Appleton hexhub wedge adapter finger tightens into connector body. Flared surface of adapter wedges box wall against locking edge of body. Forms full 360 contact on both sides of box wall. E nsulated Throat nsulating insert recessed into hex-hub wedge adapter protects against wire damage...without reduction in throat diameter. Perfect for extreme vibration conditions. Nothing to come loose, deteriorate, crack or break! PAGE 40
